FIELD: medicine.
SUBSTANCE: group of inventions refers to radiation therapy or radiotherapy, namely to systems and methods for determining target organ tracking during radiation therapy. Method of classifier training to determine quality of localization of target object on multiple images obtained by imaging device during treatment of patient by radiation therapy, comprises determining a localization result indicating a location of a target object on a plurality of images representing images obtained in a radiation therapy session, determining a quality indicator for each localization result, wherein the quality indicator represents the level of accuracy of each localization result, extraction by means of a processing circuit of one or more features from each localization result and training the classifier using the localization result, the quality indicator and one or more of the extracted features, wherein the classifier outputs an indication of the level of accuracy of the new localization result of the newly captured image. System for training a classifier for determining the quality of localization of a target object on a plurality of images obtained by a visualization device during treatment of a patient with a radiation therapy, comprises memory for storing computer-executable instructions and a processor coupled to communicate with memory, at that computer executable instructions, when executed by processor, cause processor to execute method. Non-temporal machine-readable medium stores a set of instructions, which is an executable processor of the device, to cause this device to execute the method.
EFFECT: use of a group of inventions enables fast and efficient determination of the quality of localization of a target object in an image in real time.
